General information

Fronius Symo Hybrid

Device concept Device design:

(1) Housing cover (2) Inverter (3) Mounting bracket (4) Connection area including DC

main switch (5) Data communication area (6) Data communication cover

The hybrid inverter converts the direct current generated by the PV modules into alternating current. This alternating current is synchronized with the grid voltage and fed into the public grid. Moreover, the solar energy can also be stored in a connected battery for later use.

The hybrid inverter has been developed specifically for use in grid-connected photovoltaic systems. A backup power mode is possible if the cabling is set up accordingly.

Thanks to its design and operating principle, the inverter is extremely safe both to install and to operate. The inverter monitors the public grid automatically. In the event of abnormal grid conditions, the inverter ceases operating immediately and stops feeding power into the grid (e.g. if the grid is switched off, if there is an interruption, etc.). The grid is monitored by monitoring the voltage, frequency and islanding conditions. The inverter switches to backup power mode if it has been cabled up accordingly.

Operation of the inverter is fully automatic. The inverter is designed to draw as much power from the PV modules as possible. Depending on the operating point, this power is either stored in the battery, fed into the grid or used for the household network in backup power mode.

As soon as the energy provided by the PV modules is no longer sufficient, the power from the battery is fed into the home. Depending on the setting, power may also be obtained from the public grid in order to charge the battery.

If the inverter becomes too hot, it automatically reduces the current output power or charging power, or switches to backup power mode in order to protect itself. Reasons for the inverter becoming too hot include the ambient temperature being too high or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat dissipation).

IMPORTANT! The battery must only be switched on when the inverter is in Standby mode.

Proper use The solar inverter is exclusively intended for charging a battery with direct cur-

rent from solar modules, or for converting this direct current into alternating current and feeding it into the public grid or the household network in emergency power mode. The following actions constitute improper use:

Any use above and beyond this purpose

Making any modifications to the inverter that have not been expressly ap-

proved by Fronius Installing components that are not distributed or expressly approved by

Fronius Operating the device with a battery that has not been approved by Fronius

Operating the equipment with an energy meter that has not been approved

by Fronius

Fronius shall not be liable for any damage resulting from such action. No warranty claims will be entertained.

Proper use also includes:

Carefully studying and obeying the Installation and Operating Instructions

Performing all stipulated inspection and maintenance work

When designing the photovoltaic system, ensure that all of its components are operated within their permitted operating ranges at all times.

Observe all the measures recommended by the solar module manufacturer to ensure that the solar module retains its properties in the long term.

Warning notices on the device

Observe the stipulations of the power supply company concerning energy fed into the grid, emergency power mode and the operation of storage systems.

The Fronius Symo Hybrid is a grid-connected inverter with an emergency power function – it is not a stand-alone inverter. The following restrictions must therefore be observed in emergency power mode:

Emergency power mode may be in operation for at least 1500 hours

Emergency power mode may be in operation for more than 1500 operating

hours if 15% of the duration of the inverter's grid power feed operation is not exceeded at the relevant time

There are warning notices and safety symbols on and in the inverter. These warning notices and safety symbols must not be removed or painted over. They warn against incorrect operation, as this may result in serious injury and damage.

Device concept

Device design:

(1) Battery management module (2) Side panel (3) Lid (4) Fuses (5) Data converter (6) Battery module (1.2 kWh usable

capacity)

With the market launch of its new Fronius Energy Package, Fronius is introducing an inverter that can be used to store energy. One of the key components is the Fronius Solar Battery, which contains a lithium-ion rechargeable cell. The Fronius Solar Battery supplements the Fronius hybrid inverter by adding storage functionality. This means that the solar energy from the solar modules can be stored for later use. The storage system is only suitable for operation in conjunction with Fronius hybrid inverters.

Thanks to its design and operating principle, the storage system is extremely safe both to install and to operate. A high-performance lithium-ion phosphate battery is used (LiFePO4), which is based on the latest technology and complies with the highest safety standards.

When used in conjunction with the Fronius inverter, operation of the storage system is fully automatic.

If proper charging of the batteries in the Fronius Energy Package cannot be guaranteed for an extended period of time (over several weeks or months) for any reason, we strongly recommend that the following steps are undertaken to prevent the deep discharge of the battery modules:

switch off the main switch of the Fronius Solar Battery

remove the DC fuses from the fuse holder

remove the orange power connector from the individual battery modules

Proper use The Fronius Solar Battery is exclusively intended for taking direct current from a

Fronius hybrid inverter and storing it for later use. The following actions constitute improper use:

Any use above and beyond this purpose

Making any modifications to the storage system that have not been expressly

approved by Fronius Installing components that are not distributed or expressly approved by

Fronius Operating the system with an inverter that has not been approved by Fronius

Operating the equipment with an energy meter that has not been approved

by Fronius

Fronius shall not be liable for any damage resulting from such action. No warranty claims will be entertained.

Proper use also includes:

Carefully studying and obeying the installation and operating instructions

performing all stipulated inspection and maintenance work

Observe the stipulations of the power supply company concerning energy fed into the grid and the operation of storage systems.

Increase in storage capacity

State of charge (SOC) accuracy

The storage capacity of the Fronius Solar Battery can also be increased after purchase to a maximum capacity of 9.6 kWh of usable energy. The capacity is increased by adding additional battery modules and this must be carried out by a qualified electrician. Capacity can be expanded within 2 years from the date of purchase, but a maximum of 30 months following dispatch from Fronius Austria. The capacity cannot be increased after this for technical reasons. Observe the stipulations of the distribution network operator concerning energy fed into the grid and the operation of storage systems.

Adding or replacing a memory module can lead to inaccuracies when calculating the state of charge (SOC). Straight lines and jumps can occur, in particular immediately after the upgrade. These only affect the display of the state of charge and do not affect operation of the device.

The various operating modes

Operating modes – Explanation of symbols

Solar module

Generates direct current

Inverter – Fronius hybrid

Converts the direct current into alternating current and charges the battery. Thanks to the built-in system monitoring function, the inverter can be integrated into a network using WLAN technology.

Battery

Connected to the inverter on the DC side and used to store electrical energy.

Photovoltaic system consumers

The consumers connected to the PV system (single or threephase)

Meter – Fronius Smart Meter

For optimum energy management. You can have the meter installed in a switch cabinet by your electrical installer. Energy profiling is possible through the use of several Smart Meters. Additional consumers or generators in the system can be measured and monitored.

Operating mode: Inverter

Emergency power function

The inverter is delivered ready for supplying emergency power. However, the electrical installer must set up the emergency power function in the switch cabinet. In emergency power mode, the PV system operates as a stand-alone island.

Fronius Ohmpilot

To use surplus energy to heat water.

Additional inverter in the system (e.g. Fronius Symo)

Converts the direct current into alternating current. Cannot, however, be used to charge batteries and is not available to provide emergency power.

Grid

The Fronius hybrid inverter can be used purely as an inverter without a battery connected to it.

Operating mode

- Inverter plus battery

To ensure fault-free regulation, parallel operation of several batteries is not permitted.

To optimise self-consumption in your PV system, you can use a battery as a storage system. The battery is connected to the inverter on the DC side. As a result, there is no need for multiple current conversion processes, which results in greater efficiency.

Operating mode

- Inverter plus battery and multiple Smart Meters

Operating mode

- inverter with battery, ACcoupled to another inverter

Operating mode

- Inverter plus battery and emergency power function

IMPORTANT! In emergency power mode, an increased nominal frequency is used in order to avoid parallel operation with other generators.

To ensure fault-free regulation, parallel operation of several batteries is not permitted.

When the hybrid PV system is equipped with all the available features, the inverter can:

Feed energy into the grid

Supply the devices that are connected to the PV system with power in the

event of a power failure Use any excess energy to charge the battery.

Operating mode

- Inverter plus battery, Ohmpilot and emergency power function

IMPORTANT! In a hybrid PV system with Fronius Ohmpilot and all the system

features, the Ohmpilot cannot be operated in the event of a power failure for control-related reasons. Therefore, it makes sense to install the Ohmpilot outside of the emergency power circuit.

Operating mode

- Inverter plus battery, additional inverter and emergency power function

Operating states (only for systems with a battery)

Battery system distinguishes different operating states. The current operating state is displayed on the system monitoring website or in Solar.web.

Operating state Description

The battery cannot be discharged further until charging takes place again.

The system has been put into energy saving mode.

Energy saving mode

None of the LEDs or the battery display light up1). Energy saving mode is automatically ended as soon as sufficient excess energy is available again.

Calibration mode

Deep discharge protec-

tion

The system is in calibration mode. When there is insufficient PV energy available to reach 100%, the battery is cyclically charged to 100% for internal calibration. Under certain conditions (depending on weather, microcycles, temperature, etc.), this can take an extended period of time.

The Fronius Symo Hybrid recharges the battery to counteract self discharge and maintain the minimum state of charge.

Operating state Description

Start

1) Only available for the Fronius Solar Battery.

The storage system starts from energy saving mode (standby).

Emergency power mode

Prerequisites for emergency power mode

In order to use the hybrid inverter's emergency power function, the following prerequisites must be fulfilled:

Correct cabling of the emergency power system in the electrical installation

(see document "Fronius Energy Package - Examples of emergency power switchover"). The Fronius Smart Meter must be installed at the feed-in point and con-

figured. Latest firmware on the inverter - if required, perform a firmware update.

The emergency power sticker provided with the inverter must be attached to

the electrical distributor. Select Alternative (emergency power) setup in the CONFIG menu on the in-

verter (see Installation Instructions). Change the required settings in the emergency power area in the IO mapping

menu (Fronius system monitoring web page → Settings → IO mapping → Emergency power). Set the emergency power to "Auto" in the system overview (Fronius system

monitoring web page → Settings → System overview → Emergency power operating mode).

If there are additional inverters in the system, these should be installed outside of the emergency power circuit, but within that for the Fronius Smart Meter, see

Operating mode - Inverter plus battery, additional inverter and emergency power function on page 24.

NOTE! Emergency power mode is not possible with the batteries from the LG

Chem ResuH series.

Transitioning from feeding energy into the grid to backup power mode

Transitioning from backup power mode to feeding energy into the grid

The public grid is monitored by the inverter's internal grid and system pro-

1. tection unit and by the Fronius Smart Meter connected to it.

The public grid fails or specific grid parameters are dropped below or ex-

ceeded.

The inverter carries out the measures necessary according to the country

3. standard and then switches off. The inverter starts backup power mode after a checking period.

4. All loads in the household that are in the backup power circuit are supplied

5. by the battery and the PV modules. The remaining loads are not supplied with power and are safely isolated.

The inverter is operating in backup power mode.

The public grid is functioning correctly again.

2. The Fronius Smart Meter monitors the grid parameters on the public grid

3. and passes this information to the inverter. The stability of the returned public grid is determined by checking the meas-

4. ured values of the Fronius Smart Meter. The inverter ends backup power mode.

5. All circuits are reconnected to the public grid and are supplied by the grid.

6. The inverter can start feeding energy into the grid again after performing the

7. grid checks required by the relevant standard.

Restrictions in backup power mode

In backup power mode, some electrical appliances cannot function properly as the starting currents are too high (e.g. fridges and freezers). It is recommended to switch off non-essential loads during backup power mode.

Switching from grid-connected operation to backup power mode takes a little while. For this reason, the battery system with backup power function cannot be used as an uninterruptible power supply, for example for computers.

If no energy is available from the battery or the PV modules during backup power mode, this mode is automatically ended, irrespective of whether power is available from the public grid or not. Fronius Solar Battery: If sufficient energy becomes available from the PV modules once again, backup power mode starts again automatically. BYD Battery-Box Premium: The system must be restarted manually as soon as sufficient energy from the PV modules or the public grid is available again. For the correct power-up sequence, see chapter BYD Battery-Box Premium on page

34.

If consumption is too high, backup power mode is interrupted and status code "143 - Backup power overload" appears. The maximum power in backup power mode according to the technical data must be observed!

Backup power and energy saving mode

Fronius Ohmpilot and backup power mode

If the inverter is operating in backup power mode, energy saving mode is automatically active. Under the following conditions, the battery and the inverter are switched to energy saving mode after a waiting time of 8 - 12 minutes:

The battery is discharged to the minimum state of charge and no energy is

coming from the PV modules. The inverter is in an error state that is not acknowledged automatically (e.g.

multiple overload). The inverter is set to energy saving mode (standby mode) using the display

setting.

If the battery and inverter are in energy saving mode, the system is reactivated by the following actions (applies only for Fronius Solar Battery):

Enough energy is available from the PV modules.

The public grid is functioning again.

The battery's POWER switch is switched off and on.

More information on energy saving mode can be found in chapter Energy saving

mode on page 29

The Fronius Ohmpilot is not suitable for backup power mode. If a Fronius Ohmpilot is used, it should be installed outside of the backup power circuit (see Oper-

ating mode - Inverter plus battery, Ohmpilot and emergency power function on

page 23).

NOTE!

Risk from an active Ohmpilot in backup power mode.

This may result in loss of the backup power supply.

Never turn on boost mode on the Ohmpilot.

▶

Switch off the automatic circuit breaker on the Fronius Ohmpilot (if fitted).

▶

Before a power outage occurs, any function that would exceed the power

▶

limits in backup power mode must be disabled.

Disable functions that would exceed the power limits in backup power mode:

Set measuring of heating rod to manual on the Ohmpilot (under "General -

General Settings - Heating 1 - Manual").

Disable the "Legionella prevention (h)" and "Adapt day curve" settings (under

"General - General Settings - Heating 1").

Energy saving mode

General Energy saving mode (standby) is used to reduce the self-consumption of the sys-

tem. It is available from version 1.4.1-11 of the system monitoring software. Both the inverter and the battery automatically switch into energy saving mode under certain conditions.

Fronius Symo Hybrid

If the battery is ﬂat and no PV energy is available, the inverter switches to energy saving mode. Only the inverter's communication with the Fronius Smart Meter and Fronius Solar.web is maintained.

Fronius Solar Battery and Fronius Symo Hybrid switchoff conditions

The battery state of charge is less than or equal to the input

minimum state of charge.

The power from the PV modules is less than 50 W.

The current charging or discharging power of the battery is

less than 100 W.

Less than 50 W is available for charging the battery. The

power of feeding in for the public grid is at least 50 W less than the power currently required in the home network.

If all the switch-off conditions are met, the battery switches into energy saving mode within six minutes. This time delay ensures that the inverter can be restarted at least once.

The inverter automatically switches into energy saving mode after the battery.

Backup power:

If the backup power function has been activated, the battery in grid operation does not switch to energy saving mode. Otherwise, the dark start (start without grid and PV supply) of the hybrid system cannot be ensured. During backup power mode and when the state of charge falls below the minimum limit, the battery switches to energy saving mode.

Fronius Symo Hybrid and Fronius Solar Battery switchon conditions

Special case If the inverter does not operate for 8–12 minutes (e.g.: error), or if there is an in-

If one of the following conditions is met for at least 30 seconds, energy saving mode is ended:

Energy saving mode is no longer permissible owing to a changed setting on

the user interface of the inverter. More than 50 W is available for charging the battery. The power of feeding in

for the public grid is at least 50 W greater than the power currently required in the home network. If a dynamic power reduction of 0 is set, or if the system is operating in

backup power mode, the power of feeding in for the public grid is always less than the required power in the home network. There is a separate condition for this case (dynamic power reduction < 300 W or active backup power mode): If the PV power is above a specified threshold (50 W), the energy saving mode is ended. Battery charging from the public grid is requested via the website.

The battery is recharged to restore the minimum state of charge or to per-

form a calibration. The Fronius Solar Battery is woken up as soon as the Symo Hybrid is generat-

ing PV power. This guarantees reliable operation of the battery.

Calibration charging for the Fronius Solar Battery

Benefits of calibration charging

General Determining the exact state of charge (SOC) of the battery is important for oper-

Natural differences in the individual cell capacities and the small amount of self discharge that occurs in all batteries cause the cell voltages to diverge. This makes the SOC value less accurate, which affects the operation. If no steps are taken, the battery will become damaged.

Periodic calibration charging brings all cells of the battery to the same state of charge, and calibrates the SOC value. This ensures a longer service life of the battery cells.

ation management. To ensure this happens, the battery must regularly be charged to 100%. This allows the SOC value to be calibrated.

Fronius Solar Battery:

Calibration charging occurs automatically during operation after several charge and discharge cycles. When calibration charging is carried out depends on two crucial factors:

Average state of charge

Energy throughput of the battery

As these factors are extremely weather dependent, the time of a calibration charge can vary depending on the time of year.

Conditions for starting the calibration charge (Fronius Solar Battery)

Calibration charging procedure (Fronius Solar Battery)

The following description of calibration charging is valid from version 1.4.1-12 of the Fronius system monitoring software.

One charge and discharge cycle of the Fronius Solar Battery corresponds to an energy throughput of 48 Ah per battery module. Calibration charging occurs cyclically according to the following conditions:

After 3 full charge and discharge cycles and a SOC of 80%

After 5 full charge and discharge cycles and a SOC of 50%

After 7 full charge and discharge cycles, independent of the SOC

For newly installed systems and for module replacement or expansion, a calibration charge is started automatically after 30 minutes.

Calibration charging primarily occurs with the entire PV power. If insufficient PV energy is available, energy is drawn from the public grid. This is also the case even if the "Battery charging from DNO grid" function is deactivated, as this is a critical requirement.

The SOC is calculated per battery module. For this reason, each battery module must reach a SOC of 100%.

Calibration process (Fronius Solar Battery)

The start conditions must be fulfilled

1. The battery is charged to 100% with a minimum current of 6.5 A or the total

2. PV power. So that a SOC of 100% can be reached for each battery module, one of the

3. following two conditions must be fulfilled for at least 2 minutes (for each cell in every battery module):

Minimum cell voltage ³ 3.45 V and current < 100 mA

Minimum cell voltage > 3.5 V independent of current

When a battery module reaches one of these conditions, the current is lim-

4. ited to prevent an overload. A current in the two-digit mA range ﬂows over a bypass resistor Unneeded PV power is reused directly

5. Once all cells in all battery modules have fulfilled one of the two conditions,

6. the SOC is set to 100% and calibration charging is complete.

Duration of calibration charging (Fronius Solar Battery)

Limitations during calibration (Fronius Solar Battery)

Due to tolerances in the cells, they are not always charged and discharged at the same rate. As cells and battery modules are connected in series and the slowest cell determines the charging and discharging duration, some calibration charges need more or less time.

In rare cases, calibration charges or full charge cycles (depending on the time of year, e.g. in the winter months) can lead to large variations in the cell voltages in the battery modules. In calibration mode, one cell charges more quickly than the others. This cell then begins redistribution. The other cells can then only be charged with a reduced charging current. It takes longer for these cells to reach the target value.

If the battery is regularly charged completely, calibration charges are rarely required. The cells are calibrated during every charge with 100% SOC. In the winter months. where there are few full charges and a lower energy throughput, calibration charges can take longer, as higher variations between the battery modules must be redistributed.

Drawing energy from the battery (discharging) is not possible

Self-consumption optimisation is disabled while calibration charging is in

progress Charging from the grid can still occur if the "Battery charging from DNO

grid" function is not activated, as this process concerns system-relevant service charging Zero feed-in continues according to the standard and service charging can

even be started if you wish to expand or replace battery modules during calibration Emergency power mode can be started – calibration charging is interrupted

Display during calibration charge (Fronius Solar Battery)

As soon as calibration charging starts, it becomes visible in Fronius Solar.web (current and energy balance view) or on the web interface of the Fronius Symo Hybrid inverter.

In Fronius Solar.web or on the web interface of the inverter,

the calibration charge information is displayed in the overview. Clicking on the battery symbol (see the image on the left) displays the information "The battery is in calibration mode"

In the energy balance display in Solar.web, both the start and end of the calibration charge is displayed by changing the battery status ("Battery Mode: Normal → Calibrate" and "Battery Mode: Calibrate → Normal") The following graphic shows calibration charging of the Fronius Solar Battery in the energy balance view. At the start of calibration charging, the total PV production is used to charge the battery. From the point where one cell is fully charged, only a certain charging current is drawn by the battery. This charging current decreases towards 0 A as the cell voltage increases.

As during normal operation, the status "charging" (CHG) is shown on the battery display and the relevant charging current in ampere is displayed. If the charging current drops to below 0.3 A, 0 A is shown on the display, even though calibration charging continues.

In Fronius Solar.web, the SOC value for the entire battery is displayed. On the battery display, the SOC values of the individual battery modules can be viewed.

The relay opens as soon as the power stage set registers an error and goes from normally feeding energy into the grid to being in an error state. This means that the relay can be used for fail-safe functions.

Application example

It may be necessary to perform phase compensation when using a single-phase inverter at a multiphase site. If an error occurs on one or several inverters and the connection to the grid is broken, the other inverters must also be disconnected to maintain the phase balance. The "GAF" relay function can be used in conjunction with the Datamanager or an external protection device to recognise or signal that an inverter is not feeding in or is disconnected from the grid and to then disconnect the remaining inverters from the grid using a telecontrol command.

Active output:

ON: The ﬂoating NO contact is on all the time the inverter is in op-

eration (as long as the display is not dark or is displaying something).

OFF: The ﬂoating NO contact is off.

Setting range 0 to the set switch-on point of the inverter (W or kW)

Energy Manager (under "Relay" menu item)

The "Energy Manager" function can be used to activate the ﬂoating switch con- tact in such a way that it functions as an actuator. Thus, a load that is connected to the ﬂoating switch contact can be controlled by specifying a switch-on or switch-off point that depends on the power of feeding in.

The ﬂoating switch contact is automatically switched off:

If the inverter is not feeding any power into the grid

If the inverter is manually switched to Standby mode

If the effective power is set to < 10% of the rated power

To activate the "Energy Manager" function, select "E-Manager" and press the "Enter" key. When the "Energy Manager" function is running, the "Energy Manager" symbol will appear in the top left corner of the display:

When the ﬂoating NO contact is off (open contact)

When the ﬂoating NO contact is on (closed contact)

To deactivate the "Energy Manager" function, select a different function and press the "Enter" key.

Notes on setting up the switch-on and switch-off points

The interface of the energy management relay always uses the output power of the inverter as a reference point, although this will not necessarily match what is generated by the PV system in the case of the hybrid system. If the difference between the switch-on and switch-off points is too small, or if there are ﬂuctuations in effective power, the result may be multiple switching cycles To avoid frequent switching on and off, the difference between the switch-on and switch-off points should be at least 100 - 200 W.

When choosing the switch-off point, the power consumption of the connected load should be taken into account.

When choosing the switch-on point, the weather conditions and anticipated insolation should also be taken into account.

Application example

Switch-on point = 2000 W, switch-off point = 1800 W

If the inverter is outputting 2000 W or above, then the ﬂoating switch contact on the inverter is switched on. If the inverter output falls to below 1800 W, the ﬂoating switch contact is switched off.

Possible applications: Operating a heat pump or an air-conditioning system using as much self-generated power as possible

Fronius system monitoring

General

General Fronius system monitoring is a networked datalogger.

The Fronius system monitoring web page provides a quick overview of the photovoltaic system. It can be accessed via a web browser when there is a direct connection or – if configured to support an indirect connection – over the Internet.

If the feature is used in conjunction with Fronius Solar.web, current data and archive data can be accessed for a particular photovoltaic system via the Internet or the Fronius Solar.web App without the need for any laborious configuration work. Fronius system monitoring automatically sends the data to Fronius Solar.web.

Prerequisites for operation

You must have a suitable internet connection to enable data to be exchanged smoothly over the internet:

For wired internet solutions, Fronius recommends a

download speed of at least 512 kBit/s and an

upload speed of at least 256 kBit/s. For solutions that rely on mobile internet services, Fronius recommends 3G

transmission as a minimum, plus a reliable signal.

Even if these specifications are adhered to, there is still no guarantee that everything will run smoothly. High error rates during transmission, variable reception conditions or transmission dropouts can all have a detrimental effect on the online functionality of Fronius system monitoring. Fronius recommends testing any connections that meet the minimum requirements locally.

Calculating data volumes

General When using Fronius system monitoring, data is collated that must be transmitted

over the internet. The data volume must be calculated so that the correct internet connection is selected.

The data volume calculation below provides an overview of the data quantities involved when using Fronius system monitoring.

Calculating data volumes

The data volume calculation depends on the number of connected devices in the system monitoring. The table below provides an overview of the data volume for various configurations and time settings (INV = Fronius Symo Hybrid, SM = Smart Meter, BAT = battery module of the Fronius Solar Battery)

Data volume per day:

A data volume of approx. 500 kB per hour is required to view the system on Fronius Solar.web or the Fronius Solar.web App.

A certain data volume is also required to update the Fronius system monitoring firmware. This data volume depends on the size of the update package and therefore cannot be considered in the advance data volume calculation.

If data is sent via a third-party service (e.g. push service), a large quantity of data may be involved.

IMPORTANT! Fronius recommends a ﬂat rate data connection to avoid high con- nection charges.

General information for the network administrator

Requirements NOTE! Knowledge of networking systems is required in order to configure Froni-

us system monitoring for the network.

If you are integrating Fronius system monitoring into an existing network, you must adapt the address settings in line with the network.

e.g.: Network address space = 192.168.1.x, subnet mask = 255.255.255.0

An IP address of between 192.168.1.1 and 192.168.1.254 must be assigned

to Fronius system monitoring. The selected IP address must not be in use on the network already.

The subnet mask must match that of the existing network (e.g.

255.255.255.0).

If you want Fronius system monitoring to send service messages or to transmit data to Fronius Solar.web, you must enter a gateway address and a DNS server address. Fronius system monitoring uses the gateway address for the purpose of establishing an Internet connection. An example of a suitable gateway address would be the IP address of the DSL router.

General firewall settings

IMPORTANT!

Fronius system monitoring must never be assigned the same IP address as

the PC/laptop itself! Fronius system monitoring is not capable of connecting to the Internet on its

own. In the case of a DSL connection, a router has to establish the Internet connection.

DSL routers usually allow data to be sent over the internet and so do not normally have to be configured for this purpose.

Server addresses for data transfer

If a firewall is used for outgoing connections, the following protocols, server addresses and ports must be allowed for successful data transfer:

Tcp fronius-se-iot.azure-devices.net:8883

Tcp fronius-se-iot.azure-devices.net:443

Tcp fronius-se-iot-telemetry.azure-devices.net:8883

Tcp fronius-se-iot-telemetry.azure-devices.net:443

Udp sera-gen24.fronius.com:1194 (213.33.117.120:1194)

Tcp cure-se.fronius.com:443

NTP 0.time.fronius.com

Tcp http://firmware-download.fronius.com:80

Upd/Tcp 0.time.fronius.com:123

If existing firewall rules block the connection to the Fronius system monitoring function, the following firewall rules must be added:

49049/UDP

80/TCP *)

Using Fronius Solar.web and sending service messages

output

Sending of service messages x -

Ability to connect to Datamanager via Fronius Solar.web

Ability to connect to Datamanager via Fronius Solar.access or Fronius Solar.service

Ability to access the Datamanager web page - x

Configure the firewall so that data can be sent from the Fronius system monitoring IP address to port 49049/UDP of "fdmp.solarweb.com".

*) We recommend only allowing access to the web interface of the Fronius system monitoring function from secure networks. If internet access is absolutely necessary (e.g. for service purposes within a defined time period), configure the network router in such a way that requests for any external port are redirected to port 80/TCP. Caution - the inverter will therefore be visible on the internet and at will be at an increased risk of network attacks.

An Internet connection is required if you want to use Fronius Solar.web or to send service messages.

Fronius system monitoring is not capable of connecting to the Internet on its own. In the case of a DSL connection, a router has to establish the Internet connection.

browser: http://datamanager or

192.168.250.181 (IP address for WLAN connection) or

169.254.0.180 (IP address for LAN connection)

If you run the technician wizard, always remember to make a note of the assigned service password. This service password is required to enter settings in the "System overview" and "DNO Editor" menus as well as for advanced battery settings. If the technician wizard is not run, no specifications regarding power reduction are set and hybrid mode is not possible (charging and discharging of the battery)

Run the technician wizard and follow the instructions

IMPORTANT! Danger of deep discharge of an unactivated battery

This may result in permanent damage to the battery.

The Solar Web wizard needs to be run in order to activate the battery and, if

▶

necessary, the Smart Meter.

Run the Solar Web wizard and follow the instructions

The Fronius Solar.start homepage or the Fronius system monitoring web page is displayed.

Information to help you work through the technician wizard

The technician wizard consists of 5 steps:

1. General

General system data (e.g. system name) is entered here

2. Service password

Enter (and make a note of) the service password.

3. IO assignment

Settings for the IO interface are entered (see also General for IO assignment on page 96)

4. System overview

Settings for the entire PV system are entered (see also System overview on page

111)

5. Dynamic power

Settings for dynamic power reduction are entered (see also DNO Editor – Dy-

namic power reduction on page 116)

Once you have worked your way through the technician wizard, an automatic process is triggered to calibrate all the components. This involves charging the Fronius Solar Battery fully. After that, the system automatically starts in the set operating mode. This calibration charging process is also performed automatically during actual operation after a number of charging and discharging cycles. When this calibration charge is performed depends on a number of different factors, such as the average state of charge or the energy throughput through the battery. The time can therefore vary depending on the time of year as well.

If the "permit battery charging from DNO grid" setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic system when operating under normal conditions. Depending on the insolation conditions and size of the systems concerned, the charging process can take a very long time. If the "permit battery charging from DNO grid" setting is activated, the calibration charging process is performed by drawing a constant current from the photovoltaic system and the DNO grid.

IMPORTANT! The automatic process for fully charging the battery may result in energy being drawn from the DNO grid. The process can take several hours and cannot be aborted.

Testing backup power mode

NOTE!

Danger from immediate inverter operation in backup power mode without a connection to the grid having been previously established.

During grid-connected operation, the inverter recognises and stores the direction of phase rotation in the household network. Without a grid connection, no information is available regarding the direction of rotation and the inverter feeds energy with a default direction of rotation. This can cause the three-phase consumers in the household network to experience errors.

Backup power mode should be tested once it has been installed and set up for the first time. A battery state of charge of over 30% is recommended when in test mode.

A description of how to perform the test operation can be found in the chapter "Backup power checklist" of the document "Fronius Energy Package - Examples of backup power switchover".

Settings – Passwords

General remarks Access to Fronius system monitoring is controlled by assigning passwords.

There are 3 different types of password available for this purpose:

The administrator password

The service password

The user password

Passwords Administrator password

User name = admin

The administrator password is set during the commissioning process and grants the user read access and the right to change settings. The user can open the Settings menu and enter all settings apart from those for “DNO Editor” and "Meter".

If an administrator password has been set, the user must enter the user name and password in order to open the Settings menu.

Service password

User name = service

The service password is usually assigned by the service technician or system installer when running the Setup wizard and it provides access to system-specific parameters. The service password is required to modify meter and DNO Editor settings. The "Meter" and "DNO Editor" menu items cannot be accessed unless a service password has been assigned.

User password

When the 'Protect your system monitoring from unauthorized read access' se- lection box is checked, the user password is displayed, user name = user.

If a user password has been assigned, the user only has read permissions. The user is not able to open the “Settings” menu.

If a user password is assigned, the user is required to enter the user name and password whenever they want to establish a connection.

Settings – Network

dow opens with the same setting options as with a LAN connection.

"Connect via WPS" button - To access a WLAN via WPS without needing the

WLAN password:

1. Activate WPS on the WLAN router (see documentation provided with the

WLAN router)

2. Click the 'Connect via WPS' button

3. The WLAN connection is established automatically

Internet via LAN

Setting options:

"Obtain address" - statically

The user needs to enter a fixed IP address for the Datamanager (system monitoring) and also defines the subnet mask, the gateway address and the DNS server address (from the provider). "Obtain address" - dynamically

The Datamanager (system monitoring) fetches the IP address from a DHCP server (DHCP = Dynamic Host Configuration Protocol). The DHCP server must be configured so that the same IP address is always assigned to the Datamanager (system monitoring). This means that you always know which IP address can be used to reach the Datamanager (system monitoring) datalogger. If the DHCP server supports the DNS dynamic updates function, a name can be assigned to the Datamanager (system monitoring) in the "Host name" field. As a result, the connection to the Datamanager (system monitoring) can be established using the name instead of the IP address. For example: Host name = sample_system, domain name = fronius.com The Datamanager (system monitoring) can be reached via the address "sample_system.fronius.com".

Local network via access point

The Datamanager (system monitoring) serves as an access point. A PC or smart device connects directly with the Datamanager (system monitoring). It is not possible to connect to the internet.

Settings – Fronius Solar.web

Fronius Solar.web

You can use the Fronius Solar.web menu item to establish a direct connection to Fronius Solar.web.

The storage system interval selected for the fields "Inverter Query Cycle" and "Fronius Sensor Cards Query Cycle" affects the required storage capacity.

"Register at Solar.web" button - Clicking this button opens the Fronius Solar.web homepage and any data of relevance to Fronius Solar.web is sent automatically at the same time.

Settings – IO mapping

General This menu item allows you to configure the properties of the inverter's individual

inputs and outputs (I/O). You can only select those settings that are supported by the system concerned (which are determined by the functionality of the system and how it has been configured).

An active output that has not been assigned (is "free") remains active until the inverter is restarted. The status of an output only changes in the event of new specifications for assigned services.

The remote control capability of the inverter always relates to the nominal device output.

IMPORTANT! If no DRM control (DRED) is connected to the Datamanager and the "AUS - Demand Response Mode (DRM)" function is activated, the inverter switches to standby mode.

Energy storage device

The pin for activating the energy storage device can be selected here. This setting only needs to be made for certain energy storage devices.

If an energy storage device pin is set, then emergency power pins cannot be configured.

Settings - load management

Load management

Energy management controlling priorities

If additional components (e.g. battery, Ohmpilot) are available in the system, the priorities can be set here. Devices with a higher priority are activated first, followed by the others if surplus energy is available.

Load management

Up to four different load management rules can be defined. If the thresholds are the same, the rules are activated in sequence. During deactivation, it is the other way round; the last IO switched on is the first to be switched off. If the thresholds are different, the IO with the lowest threshold is switched on first, followed by the one with the second lowest threshold and so on.

IOs which are controlled through the power produced are always at an advantage over the battery and Ohmpilot. This means an IO can switch itself on, resulting in the battery no longer being charged or the Ohmpilot no longer being activated

An IO is only activated or deactivated after 60 sec.

Control

Control via Energy Manager deactivated.

Control via Energy Manager is based on the power produced.

Control via Energy Manager is based on surplus power (with feed-in limits).

This option can only be selected if a meter has been connected. Control via Energy Manger is based on the amount of energy actually fed into the grid.

Thresholds

on: For entering an effective power limit as of which the output is to be activ-

ated off: For entering an effective power limit as of which the output is to be de-

activated.

Duration

Field for activating the minimum running time per switch-on operation

Field for specifying the minimum amount of time that the output should re-

main activated for per switch-on operation. Field for activating the maximum running time per day

Field for specifying the maximum total amount of time that the output

should be activated for per day (allowing for several switch-on operations).

Desired duration

Field for activating a desired running time
